Abstract

Abstract : A new compact dual wideband CPW‐fed inverse triangular‐shape antenna is presented. The lower and upper bands are widened from 68.76 and 18.33% to 96.23 and 28.7%, respectively, using a triangular patch‐trapezoidal ground combination. The antenna performance is further enhanced by backing it with a dual‐band uni‐planar EBG reflector. The final design has been prototyped and measured. It sufficiently covers the frequency bands 1.5–5.63 GHz and 9.52–13.06 GHz with enhanced gain up to 5.2 dB. The radiation efficiency is improved to approximately 72%.
